the issue here is people who dont know what they are doing and doing it wrong
it is SO easy to come up with a better idea here....i mean really
and both my floor jacks work just fine under the pinch welds if i orient the pad at the lift point properly to fit over the pinch weld....but i guess that just goes back to experience buying the right jack so ya dont have this issue
are the pinch welds smashed flat on my car???
are they a little beat up from lotsa use???
do i use an old hockey puck on the lift pad when i lift it under the rear end or the jack plate up front??
but what do i know, anyway....
